 buildozer android debug

-Generate a debug version package while displaying BUILDLOG on the screen (generated under BIN in the current directory)

4. Signing the release version

-The release version cannot be installed without a signature, so you need to sign it. If you have a formal certificate, use it, if not, generate an appropriate certificate (if you want to install and run it for the time being).

console

jarsigner -keystore keystorename -verbose touchtracer-1.2.0.apk touchtracer

5. Full screen support

To turn off the navigation bar, add the code below. However, at the moment, when the on-screen keyboard is displayed, the navigate button is displayed.
